"Google Analytics - tracking by country",
"I'm working on an international website. \nTo support multiple countries and language, a page URL looks like that:\n\n\n www.example.com/fr-en/Page\n\n\nwhere \"fr\" is the country code and \"en\" is the page language.\n\nWould it be possible to add a specific google tracking code for each country ?\n\nI would need that in order to give Google Analytics access for each of the countries dealers, where they will be able to view only their country traffic stats.\nOf course, I will also need a Google Analytics account for all of the site traffic (for all countries)."

"Download TFS 2015 Build Agent without TFS 2015 install",
"We currently use TFS 2013 with a suite of XAML builds, there are a few hundred projects here, each with an average of six build definitions each.\n\nWe're wanting to upgrade to TFS 2017 (2018 doesn't support XAML) but need to be able to support the XAML builds until they're all migrated.\n\nAccording to MS, we can setup a TFS 2017 box, a build server with a 2017 build agent on it and a separate build server with a 2015 build agent on it which TFS can use to run the XAML builds.\n\nMy problem is... where to get the 2015 build agent installer from. Normally you ask TFS for the build agent installer, but we don't have a TFS 2015 installation.\n\nAm I going to have to setup a TFS 2015 VM just so I can click one lousy link and download one installer. I've searched around but can't find any other place to get the damned thing from.\n\nAnyone got a link to an MS page?"

"How to test main function in gin application?",
"How can I test func main? Like this:\n\nfunc main(){\n Engine := GetEngine() // returns gin router with handlers atttached \n Engine.Run(\":8080\")\n}\n\n\nIt has only 2 lines but I'd like to have them covered. \nTestMain' is reserved for test preparation, does that mean testing main was not planned by language creators?\nI can move the contents to another function mainReal but it seems to be some over engineering?\n\nHow to test gin has started well? Can I launch main in separate goroutine, check reply and stop it?\n\nThanks. \n\nP.S. Possible duplicate is not precise duplicate because it is dedicated not to testing of func main() itself, but rather ideas to move in outside and so contains different issue and approach."

"so I am currently trying to do something like A**b for some 2d ndarray and a double b in parallel for Python. I would like to do it with a C extension using OpenMP (yes I know, there is Cython etc. but at some point I always ran into trouble with those 'high-level' approaches...). \n\nSo here is the gaussian.c Code for my gaussian.so:\n\nvoid scale(const double *A, double *out, int n) {\n int i, j, ind1, ind2;\n double power, denom;\n power = 10.0 / M_PI;\n denom = sqrt(M_PI);\n\n #pragma omp parallel for\n for (i = 0; i < n; i++) {\n for (j = i; j < n; j++) {\n ind1 = i*n + j;\n ind2 = j*n + i;\n out[ind1] = pow(A[ind1], power) / denom;\n out[ind2] = out[ind1];\n }\n }\n\n\n(A is a square double Matrix, out has the same shape and n is the number of rows/columns) So the point is to update some symmetric distance matrix - ind2 is the transposed index of ind1.\n\nI compile it using gcc -shared -fopenmp -o gaussian.so -lm gaussian.c. I access the function directly via ctypes in Python:\n\ntest = c_gaussian.scale\ntest.restype = None\ntest.argtypes = [ndpointer(ctypes.c_double,\n ndim=2,\n flags='C_CONTIGUOUS'), # array of sample\n ndpointer(ctypes.c_double,\n ndim=2,\n flags='C_CONTIGUOUS'), # array of sampl\n ctypes.c_int # number of samples\n ]\n\n\nThe function 'test' is working smoothly as long as I comment the #pragma line - otherwise it ends with error number 139. \n\nA = np.random.rand(1000, 1000) + 2.0\nout = np.empty((1000, 1000))\ntest(A, out, 1000)\n\n\nWhen I change the inner loop to just print ind1 and ind2 it runs smoothly in parallel. It also works, when I just access the ind1 location and leave ind2 alone (even in parallel)! Where do I screw up the memory access? How can I fix this?\n\nthank you!\n\nUpdate: Well I guess this is running into the GIL, but I am not yet sure...\n\nUpdate: Okay, I am pretty sure now, that it is evil GIL killing me here, so I altered the example:\n\nI now have gil.c:\n\n#include <Python.h>\n#define _USE_MATH_DEFINES\n#include <math.h>\n\nvoid scale(const double *A, double *out, int n) {\n int i, j, ind1, ind2;\n double power, denom;\n power = 10.0 / M_PI;\n denom = sqrt(M_PI);\n Py_BEGIN_ALLOW_THREADS\n #pragma omp parallel for\n for (i = 0; i < n; i++) {\n for (j = i; j < n; j++) {\n ind1 = i*n + j;\n ind2 = j*n + i;\n out[ind1] = pow(A[ind1], power) / denom;\n out[ind2] = out[ind1];\n }\n }\n Py_END_ALLOW_THREADS\n}\n\n\nwhich is compiled using gcc -shared -fopenmp -o gil.so -lm gil.c -I /usr/include/python2.7 -L /usr/lib/python2.7/ -lpython2.7 and the corresponding Python file:\n\nimport ctypes\nimport numpy as np\nfrom numpy.ctypeslib import ndpointer\nimport pylab as pl\n\npath = '../src/gil.so'\nc_gil = ctypes.cdll.LoadLibrary(path)\n\ntest = c_gil.scale\ntest.restype = None\ntest.argtypes = [ndpointer(ctypes.c_double,\n ndim=2,\n flags='C_CONTIGUOUS'),\n ndpointer(ctypes.c_double,\n ndim=2,\n flags='C_CONTIGUOUS'),\n ctypes.c_int\n ]\n\nn = 100\nA = np.random.rand(n, n) + 2.0\nout = np.empty((n,n))\n\ntest(A, out, n)\n\n\nThis gives me \n\nFatal Python error: PyEval_SaveThread: NULL tstate\n\nProcess finished with exit code 134\n\n\nNow somehow it seems to not be able to save the current thread - but the API doc does not go into detail here, I was hoping that I could ignore Python when writing my C function, but this seems to be quite messy :( any ideas?

I figured this would be a pretty simple thing to achieve however it's proving not to be. Here is my issue. \n\nWhen I use a .changed event and try to seralize the form before posting it. I get nothing but empty strings. I've noticed that if I hard code the post variables everything works just fine. Is there something I'm missing? Does .changed not have a seralize method?\n\nI am also using a CURL bridge since the server with the data is on another domain. I don't think that is causing any issues though. I believe it has to do with my event choice.\n\nHere is the code: \n\n $('#selector').change(function() {\n $.ajax({\n type: \"post\",\n dataType: 'json',\n url: \"/pages/curlbridge.php\",\n data: $(\"#queryform\").serialize(), //\"select=all&date=2013\"\n success: function(data)\n {\n console.log(data);\n var resultset = data;\n\n }\n });\n\n\nWas Asked to attach the HTML.

As a first step towards fixing it, I need to monitor the traffic on the IP port the service is using to talk to the controller, so that I can establish a baseline and then verify a fix.\n\nCan anyone recommend a utility and/or coding technique that I can use to get the traffic stats?

"How to get the data object from a single record in the model?",
"Recently this became a bug in my application, although I don't know what changed to make it so (I haven't upgraded the version of Ember, which is still 1.13). What I need to find out is how to access the object of a single record on the model in the conventional way.\n\nI have the following code to filter my model based on two other properties:\n\n recordsBySelectedShapeAndColor = get(this, \"model\").filter(function(rec) {\n //filter the model by the chosen shape and color\n return (\n get(rec, \"shape\") === theShape &&\n get(rec, \"color\") === theColor\n );\n });\n\n\nI then need to create a summary of those filtered records, which I'm using reduce() for, but if that filter returns only one record, then reduce doesn't return the right results, so I have the following condition:\n\nif (recordsBySelectedShapeAndColor.length < 2) {\n summary = recordsBySelectedShapeAndColor[0]._data;\n} else {\n summary = recordsBySelectedShapeAndColor.reduce(function(a, b) {\n...\n}\n\n\nIt's the line within the if that is no longer returning the a simple object, so I changed it to summary = recordsBySelectedShapeAndColor[0]._internalModel._data; and it works, but it seems fishy (._data always did too).

The classes are references to the same table, just referenced in different .edmx files.\nSimply removing one of the references is not a good option in this case as we have used a similar strategy with several other tables and would require thousands of lines of rewritten code.\nWhat do I need to do to fix this in EF6?"

"Problem with equals() method in Hibernate",
"I am developing an application in Hibernate where I have model classes like these:\n\npublic class Employee\n{\n private int ID;\n private String name;\n private Department department;\n //other properties\n //constructors, getters and setters\n}\n\n\nNote that the ID is not a value populated by the user and is populated using GenerationType.Identity as the strategy.\n\nAlso I have another class Department as follows:\n\npublic class Department\n{\n private int ID;\n private String name;\n\n private Set<Employee> employees; //this is actually a HashSet\n\n //other implementations\n}\n\n\nThere is a ManyToOne bi-directional relationship between an Employee and a Department.\n\nSo to add a new Employee to an existing Department, I do the following\n\nDepartment existingDepartment = ...;\nEmployee newEmployee = ...;\n\nexistingDepartment.addEmployee(newEmployee);\nemployee.setDepartent(existinDepartment);\n\nsession.save(newEmployee);\n\n\nNow conceptually two Employee objects are the same if they have the same ID. So my equals() method in the Employee class looks like this:\n\npublic boolean equals(Object o)\n{\n if(!(o instanceOf Employee))\n {\n return false;\n }\n\n Employee other = (Employee)o;\n\n if(this.ID == o.etID())\n {\n return true;\n }\n\n return false;\n}\n\n\nNow the problem is when I create a new Employee(); I do not have its ID, since it will be assigned when it will be persisted. So when I say \n\nexistingDepartment.addEmployee(newEmployee);\n\n\nthe internal HashSet of the Department object is effectively using an equals() method which is broken [since it uses a member variable to determine equality that as not been initialized properly].\n\nThis seems like a very basic problem but, how do I solve it? Or am I designing my classes totally wrong? Or should my equals method be re-written to compare other values instead of ID, which I guess would be absurd."

"Java method keyword \"final\" and its use",
"When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example:\n\ninterface Garble {\n int zork();\n}\n\ninterface Gnarf extends Garble {\n /**\n * This is the same as calling {@link #zblah(0)}\n */\n int zblah();\n int zblah(int defaultZblah);\n}\n\n\nAnd then\n\nabstract class AbstractGarble implements Garble {\n @Override\n public final int zork() { ... }\n}\n\nabstract class AbstractGnarf extends AbstractGarble implements Gnarf {\n // Here I absolutely want to fix the default behaviour of zblah\n // No Gnarf shouldn't be allowed to set 1 as the default, for instance\n @Override\n public final int zblah() { \n return zblah(0);\n }\n\n // This method is not implemented here, but in a subclass\n @Override\n public abstract int zblah(int defaultZblah);\n}\n\n\nI do this for several reasons:\n\n\nIt helps me develop the type hierarchy. When I add a class to the hierarchy, it is very clear, what methods I have to implement, and what methods I may not override (in case I forgot the details about the hierarchy)\nI think overriding concrete stuff is bad according to design principles and patterns, such as the template method pattern. I don't want other developers or my users do it.\n\n\nSo the final keyword works perfectly for me. My question is:\n\nWhy is it used so rarely in the wild? Can you show me some examples / reasons where final (in a similar case to mine) would be very bad?"

"Microsoft Dependency Injection & HttpClientFactory w/ .NET Framework 4.6+ / MVC 5.2 / Web API 2",
"Our web application is built on the .NET Framework 4.6+. We're using WebForms, MVC 5.2, and Web API 2.\n\nI'm in the process of trying to integrate Microsoft.Extensions.DependencyInjection and Microsoft.Extensions.Http into this solution so we can take advantage of the new HttpClientFactory that's in ASP.NET Core. We also want to start using DI in our MVC and API controllers.\n\nIt appears there are two ways this can be achieved:\n\n\nWrite a custom ControllerActivator\nWrite a custom DependencyResolver\n\n\nBased on the reading I've done, it appears the ControllerActivator method is the old way of doing this, and the DependencyResolver is the current, preferred way of handling this. I've written code for both, and both methods appear to work.\n\nConsidering the DependencyResolver appears to be the preferred solution for DI now, I'd like to use it but I'm not sure if I'm handling scope object disposal correctly.\n\nHere's how I'm configuring the DependencyResolvers in Global.asax:\n\nWeb.Mvc.DependencyResolver.SetResolver(New Mvc.DependencyInjection.DependencyResolver(serviceProvider))\nGlobalConfiguration.Configuration.DependencyResolver = New Api.DependencyInjection.DependencyResolver(serviceProvider)\n\n\nMy System.Web.Http.Dependencies.IDependencyResolver implementation for Web API is:\n\npublic class DependencyResolver : IDependencyResolver\n{\n private IServiceProvider ServiceProvider { get; }\n\n public DependencyResolver(IServiceProvider serviceProvider) => ServiceProvider = serviceProvider;\n\n public IDependencyScope BeginScope() => new DependencyResolver(ServiceProvider.CreateScope().ServiceProvider);\n\n public void Dispose() => (ServiceProvider as IDisposable)?.Dispose();\n\n public object GetService(Type serviceType) => ServiceProvider.GetService(serviceType);\n\n public IEnumerable<object> GetServices(Type serviceType) => ServiceProvider.GetServices(serviceType);\n}\n\n\nMy System.Web.Mvc.IDependencyResolver implementation for MVC is:\n\npublic class DependencyResolver : IDependencyResolver\n{\n private IServiceProvider ServiceProvider { get; }\n\n public DependencyResolver(IServiceProvider serviceProvider) => ServiceProvider = serviceProvider;\n\n public object GetService(Type serviceType) => ServiceProvider.GetService(serviceType);\n\n public IEnumerable<object> GetServices(Type serviceType) => ServiceProvider.GetServices(serviceType);\n}\n\n\nThe System.Web.Http.Dependencies.IDependencyResolver interface has Dispose(), and it appears API requests do call my implementation's Dispose method. So that appears to be working (I think).\n\nMy concern is the System.Web.Mvc.IDependencyResolver interface doesn't have Dispose(), I'm not clear if these service objects are being properly disposed after a MVC request.\n\nIf anyone can provide some insight into this I'd really appreciate it. Don't want to roll this out and find out we're leaking memory."

"I want to run a delay function for five seconds in JavaScript which will print "Hello" in the console after every second for five times.\nSimilar Python Code:\nfrom time import delay\n\nfor I in range(5):\n print("Hello")\n delay(1)\n\nThe above code will print "Hello" five times with one second delay between each print.\nNow I want to do similar kind of operation in JS.\nNow in JS we have setTimeout function which will call a function after after a specified time. The following code will print "Hello" in the console after 1 second interval.\nsetTimeout(function(){ \n console.log("Hello"); \n }, 1000);\n\nHow can I run this code that will print 'Hello' in the console five times with an one second delay between each print?\nNB: I tried to pass this function inside a for loop, but it did not work."

"Implement virtual function inherited from A using concrete function inherited from B",
"Suppose I have an interface class and a partial implementation class. Also, suppose that I absolutely do not want this partial implementation to inherit from the interface:\n\nclass interface {\n virtual void fnA() const = 0; \n virtual void fnB() const = 0; \n};\n\nclass partialImplementation { //Do not want to inherit from interface!\n void fnA() const {cout << \"fnA from partial implementation\" << endl;}\n //fnB() not implemented\n};\n\n\nThe idea is that I'm planning to make several new classes all inheriting the interface, but I want to implement the same fnA() in each one. So, after inheriting the interface, maybe I could also inherit the partial implementation and hope that fnA() gets implemented. For example,\n\nclass myClass : interface, partialImplementation {\n //would like fnA() to be implemented by partialImplementation\n void fnB() const {cout << \"fnB from myClass\" << endl;} \n};\n\n\nOf course, if you try to instantiate this class, you get this error:\n\nmain.cpp: In function 'int main()':\nmain.cpp:235:10: error: cannot declare variable 'm' to be of abstract type 'myClass'\nmain.cpp:201:7: note: because the following virtual functions are pure within 'myClass':\nmain.cpp:193:15: note: virtual void interface::fnA() const\nCompilation failed.\n\n\nAfter reading some other stackoverflow posts (like this one) it seems the only available solution is to do this:\n\nclass myClass : interface, partialImplementation {\n public:\n void fnB() const {cout << \"fnB from myClass\" << endl;} \n void fnA() const {\n partialImplementation::fnA();\n }\n};\n\n\nIn the linked post, the OP didn't mind typing three extra lines. But you could imagine that I actually want partialImplementation to implement more than just one function, and that I could be typing this same boilerplate over and over every time I want to make a new class inheriting this interface.\n\nDoes anyone know a way to do this without requiring partialImplementation to inherit from interface?"

"How do I get specific data from my localstorage so I can show them in a modal in JavaScript?",
"for example, let's say I have:\nstudent[ id : 1, Name: Jake]\nstudent[ id : 2, Name: John]\nso far what I have is\n const link = document.createElement("a");\n link.href = "#";\n link.addEventListener("click", function(){openModalCallback()}, false);\n link.textContent = student.id; \n\n let row = document.createElement("tr");\n let cell = document.createElement("td");\n \n row.appendChild(cell);\n cell.append(link);\n\nthis just opens the modal that contains the data. How do I specifically access the 2nd student when I click on his ID so only his data will be shown in the modal?"

"Accessibility and Access",
"I'd like to add some accessibility features to my Access forms, for users that have difficulty with the standard 11pt-font, white-background, black-text set-up.\n\nWindows itself has a bunch of Display Settings options for altering window font sizes, background colours etc, but these don't cover Access forms altogether well - they'll change the colour of items where system colours are used, but font face or size of labels, input boxes, data grids etc can't be changed this way as they're not connected to those settings. The Datasheet settings under File -> Options seem to have no effect on datasheet forms (or subforms).\n\nI can't find any accessibility options in Access, not so much as a Zoom function (1998 called, it wants its GUI back, etc etc). It seems ridiculously excessive to have to fire up the VBA editor and do something like:\n\nPublic Sub AccessbilityBtn_Click()\n Me.Detail.BackColor = RGB(whatever)\n\n Me.HeadingLbl.FontSize = 18\n Me.HeadingLbl.Width = 'whatever accomodates bigger text\n Me.HeadingLbl.Height = 'whatever accomodates bigger text\n Me.FieldLabel1.FontSize = 14\n Me.FieldLabel1.Width = 'whatever accomodates bigger text\n Me.FieldInput1.Width = 'whatever accomodates bigger text\n\n '... to infinity and beyond ...\nEnd Sub\n\n\nOr to craft FormName_BigText versions of every single form and replicate the entire behaivour of my entire system.\n\nSo, does Access have accessibility options? If so, where are they? And can they be called from VBA? If not, how can accessibility options be implemented into Access forms?"
